What I expected to happen was
Everything would be normal

What actually happened was
Water wen through blocks,ladder were in mid air, and the character disappears when going high.
Steps to Reproduce:
1. Goto Realms server If you put water near something like wood it may break through it.If you try to block it it wont stop this happens sometimes.
2.Go on realms then put a block and a ladder and break the block keep repeating until the ladder stays there.You will be able to go on it like if there was a block behind it.
3.Goto a realms server in creative go up high in third person then your character will disappear.
